I had two phone numbers, one was my Vonage number and the other was my verizon number. I decided to use the LNP and transfer my verizon number over to Vonage. Vonage told me that I would have to take my Vonage number and make it virtual and make the verizon number primary. I told them I would only consider this as long as I would keep my Vonage number. They made a "mistake" and instead of making my Vonage number permanent they gave it away! When I told them I wanted the number back they told me they had already given it to someone else and "can't take away a phone number from a customer", well what the heck did they do to me. So far they have not done anything to resolve this and needless to say I am pretty steamed.
